What the work involves
For England, Approved Document F gives minimum intermittent extract rates: 15 litres a second for a bathroom, 30 for a kitchen with a cooker hood (60 without one), 30 for a utility room and 6 for a WC. Wales, Scotland and Northern Ireland have their own rules, which we follow where the job is.
Like-for-like replacement
A new fan on the existing duct and wiring, often with an overrun timer or humidity sensor.
New fan through an outside wall
Core drilled, sleeved, wired from a fused spur and sealed outside.

Questions from Portland
How do I get a price for new extractor fans in Portland?
Use the guide price tool, the form on this page, live chat, WhatsApp or call 0800 088 6341. A postcode and a couple of photos help us give you a useful answer first time.
Can an extractor fan vent into the loft?
No. A fan should discharge to outside, because warm, moist air dumped in the loft condenses on the cold roof timbers and causes mould and rot there instead.
Should I get a fan with a humidity sensor?
A humidistat fan switches on when the air gets damp and runs until it clears, which suits family bathrooms and rentals where people forget the switch. A continuous-running fan is another good option.
